In this paper we present an algorithm for computing Hecke eigensystems of Hilbert-Siegel cusp forms over real quadratic fields of narrow class number one. We give some illustrative examples using the quadratic field Q(5√). In those examples, we identify Hilbert-Siegel eigenforms that are possible lifts from Hilbert eigenforms.
